5. Over Voltage Protection
protection circuit by zener diode. If zener diode is
opened, Vcc rise up, it becomes possible to
implement an over voltage protection. Ratch on
mode. If zener diode is short, output is shorted.
Protection.
6. Over Temperature Protection
analog circuit that turns the output MOSFET off
when the junction temperature exceeds the thermal
shutdown temperature (130℃ Min. , 140℃ Typ. and
70℃ hysteresis). When the junction temperature
cools to below the hysteretic temperature, normal
operation resumes providing automatic recovery.
7. Line Regulation
voltage change when the input volt is slowly varied
with in the input voltage range.
8. Load Regulation
voltage value change when varying the load current
slowly within the standard output current range.
9. Isolation Resistance
500 VDC when tested with DC isolation between the
output and the case. Make sure that during testing,
the isolation tester does not produce a high pulse
when the applied voltage is varied. Ensure that the
tester is fully discharged after the test.
It becomes possible to implement a short circuit
Maximum line regulation is maximum output
Maximum load regulation is maximum output
SFS series are equipped with an over-voltage
Temperature protection is provided by a precision
The isolation resistance is more than 100MΩ at
10. Withstand Voltage
(10mA) 1 minute between input output for the
withstand voltage test, the applied voltage must
be increased gradually from zero to the testing
value, and then decreased gradually at shut
down. Especially stay away from use of a timer.
Where a pulse of several times the applied
voltage can be generated.
11. No-Load Power Consumption
when it is disconnected from it's load and
performing no function.
12. Short Circuit Protection
activity, the IC is able to detect the presence of
a short-circuit. Immediately reducing the output
power for a total system protection. Once the
short has disappeared, the controller resumes
and goes back to normal operation.
SFS5 series are designed to withstand 3KVAC
No-Load power is the energy used by a device
By permanently monitoring the feedback line
